Abstract
The influence of polymer modification on the fracture parameters of high-strength concretes was investigated. Fracture toughness test was conducted for various types of specimens which vary the matrix strength, the type of coarse aggregate and the polymer content. Fracture parameters for the high-strength concretes were analyzed based on the poly-linear approximation analysis of the tension softening diagram with the data of load-load point displacement curves. The tensile strength, fracture energy, toughness modulus and crack resistance of the high-strength concretes were improved by adding the appropriate amount of polymer in paste matrixes. The use of polymer was effective in the case of the high-strength concretes containing high-strength aggregate.
